Embodiment Construction

[0069] The new waveform has been named the "Gauss-Rees" waveform. This waveform can be characterized as follows.

[0070] Gauss-Rees waveforms and their associated quasi-Ricker wavelets:

[0071] The Gauss-Rees waveform has an analytical form given by the following equation.

[0072] ψ(t)=g 1 / 2 (t){1-(2at)exp[(1-(2at) 2 ) / 2]} 1 / 2 exp(iω 0 t)

[0073] Therefore, its real part is given by

[0074]

[0075] Among them, by letting the bandwidth of the envelope of the Gauss-Rees waveform take cycle / second = Hertz as the unit, such as ω 0 =2πf 0 , so that f in Hertz 0 Also determines the center frequency of the carrier of the Gauss-Rees waveform, and the constant "a" determines the time scale of the waveform. It should be noted that a direct current (DC) offset, denoted by a single value preceding the exponent within parentheses, is applied to not only achieve but also avoid greater than 100% amplitude modulation that would introduce sideband "jamming" of the carrier....

Abstract

Gauss-Rees waveform utilization in identifying an object, includes: directing a primary acoustic waveform at the object to produce a nonlinear acoustic effect; receiving a secondary wavelet produced by the nonlinear effect; and processing the received secondary wavelet in identifying the object. The object is identified by composition, image, and preferably both. The object can be concealed in a container, underground, under water, or otherwise.
